I suggest C Interfaces and Implementations: Techniques for Creating Reusable Software by David Hanson.[1] It focuses on helpful engineering practices for reliably and efficiently implementing algorithms in C. I also second the recommendation for Peter van der Linden's Expert C Programming for its masterful treatment of how C really functions, including the surprisingly frequent areas in which real-world constructs produce "undefined behavior" from the perspective of the C standard.
